The invention relates generally to foundry.

ladles. More particularly theV invention relates to that type of ladle which is designed for use in foundries in connection with the la pouring of molten metal into molds and is kno-wn as a tea pot ladle.

In practice it has been found in connection with the use of a ladle of this type that cold heats and delays cause the molten metal and slag to freeze in the restricted duct in the spout of the ladle and results in the formation of skulls which cannot be easily removed and frequently render it necessary to destroy the entire ladle-lining in removing them.

One object of the invention is toprovide a ladle of the type under consideration which embodies an improved spout construction whereby it is possible to remove the skulls, Y without destroying. the spout-lining. An- 2-0 other object of the invention is to-provide-a foundry ladle of the tea pot typein which the spout consists' of separable sections Vof novel design and is constructed that access may be readily had to the duct or Opening between the interior of the ladle andthe entrance or inlet end of the spout.

Other objects of thek invention and the various advantages and characteristics'of the present ladle construction will be apparent from a consideration of the following detailed description.

The invention consists in the several novel features which are hereinafter set forth and more particularly defined by the claims at the 8'5 conclusion hereof.

In the drawing which accompanies and forms a part of this specification or disclosure and in which like numerals of reference denote corresponding parts throughout thel several views: Fig. 1 is a plan of a ladle embodying the invention. Fig. 2 is a side elevation, parts being omitted for. purposes of illustra tion. Fig. 3 is a perspective of the portion of the pot which is provided with the fixed section of the spout. j Fig. 4 is a perspective o-f the removable section of the spout.

The ladle which forms the subject matter of the invention is adapted to be used in foundries in connection with the pouring of molten metal into molds and comprises a pot o. The latter consists of a metal jacket or shell 7 and arefractory lining Sand is pivotally supported bytrunnions 9 in a bail 10 so that it may be tilted to discharge the metal therefrom, by suitable gearing which is enclosed" in 'a casing 11' and is operable bya hand-wheel 12. The manner of pivotally Y supporting thev ladle and the mechanism or gearing for effecting thedesired tilting may be of any suitable construction,aas well un-A derstood in the art.

In addition to the pot, the ladlefconiprises i a spout. The metal flows to the spout through an outlet yduct 13 which is locatedimmediately above the bottom of the pot and -extends through the lining V8 and the shell 7, to avoid discharging the slag on theltop portion of l the molten metal. 'A discharge duct 14leads upwardly from the duct 13 to a point adjacent drawn from the bottom of the pot and be discharged Ona line approximately level with the top of the pot. Inpractice it has been foundv that cold heatsor delays frequently cause the metal or slag to' freeze in the ladle and this freezing usually starts'in the outlet `away therewith, so that in mostlinstances "theentire lining of the pot and spout must be replaced'. So that theA` spout may be cleared andr itsr lining separated from the lining in the pot, the'fspout is disposed outside of thei shell 7,-and is split or formedwith a removable section. One section of vthe spout is formed-of a plate of metal 15 which-is shaped to extend under thegduct 13 and extends upwardly, as at 16, to form the sides o f the fixed section of the -spout which are adapted to retain a portionl of the spout-lining outside of thev shell 7. Theplate15 is provided with a flange 17 to fitv the outer peripheryof the shell 7 and is riveted thereto.I Itis also flanged, as at 18, along a vertical plane intersecting the duct 14 longitudinally. The fixed section 'of the" spout contains,Y outsidel ofthe to the topl of the pot so the metal will ybe 7G outwardly away from the spout while it isrv, being poured. The flanges 18 onV the fixedVj shell 7, a lining 19 of suitable refractory material forl the .duct 13 and the portion of the duct 14 that is adjacent to the pot. The outer side or section of the spout extends vertically and consists of a metal plate 20,l

whichis provided withrintegral sideY flanges 21 andv supports a refractory lining 22. The side flanges 21 register with the flanges 18 of the plate 15. The upper end of platev and-its liningl 22 'are curved outwardly tov form a discharge lip for-directing the'metal spout section are provided with holes 28 and the flanges 21'on the removable sectionare' provided with corresponding holes 424. Pins 25'having heads at their outer ends, are 'adapted to pass through holes 23 and24, and Wedgekeys 26 in slots in the lpins are adapted to y,draw the pins to secure 'the' flanges together and thus'loc'l: the removablefspout section j the openingl ductV 13 is readily accessible so the slag orskulls can beremoved-therefrom by a suitable tool inserted from the outside. 'Therskullseor slag `adhering to ,theV llnings 19v and 22 can be easilyremoved because they arey readily accessible' when the removable spout section has been disconnected from the pot, 6. The greatest accumulation Yof skulls usually-forms in the spout and sometimes in their removal, the linings 19, 22 are destroyed but it is not necessaryto, destroy the potvlin- Y ing in doing so. It is only necessary to replace the spout lining because it is outside of the pot -so that'thepot lining will not bedevstroyed in the removal of skulls and lining from the spout. The spout sections when separated can be easily r'elined. In replacing the removable, spout section, the meeting faces of the lining 19, 22 in the section arevcoated with mud or canister as previously pointed out so as to form a seal between them. The invention exemplifies a pouring ladle i" of the tea pot type which is provided with a spout of improvedV design having a lining which can be removedwithout destroying the pot lining. i. Y l
